If we are playing in a system where a team that loses to another team and doesn't even play for their conference championship gets a rematch with the opportunity to win it all. I hardly think you can object to KSU claiming a three way title.
Also. I don't see this as being one of the last BIG 12 championships for years to come. In time it will just blend into championship landscape. I think we can pull down 1 or two a decade.
Getting a BIG 12 championship and then playing Arkansas in the Cotton and beating them? Way better than any BCS win that we could hope to pull off.
